After HTTYD 3, when Hiccup and Toothless supposedly split, Toothless follows the Light Fury down into the Hidden World. The story follows the awkwardly cute romance between them, but also has some *ahem* Mature Scenes. (Also, since the Light Fury has yet to be named, I am calling her Twister.)

Hiccup and Toothless have just beaten the Evil Bewilderbeast and Drago Bludvist. When Hiccup becomes chief and Toothless the alpha dragon. They were helping clean up the village along with Valka and Gobber and their dragons Cloudjumper and Grump. Nothing out of the ordinary until a black blur flies across the sky.

This book was terrible, go check out my other book, that is way better.

Before the red death,when Toothless was born, there were four ruling Nightfurys. But then the red death came, and only two survived. One a son, the other daughter. This is How to train your dragon 3.

Toothless is checking an island far from Berk. He is alone because hiccup is too busy at the village. He landed near the forest and he smell fresh blood. He follows the smell and it leads him to a cave. He looks in the cave but saw nothing. Suddenly a dragon jump on top him and pinned him to the ground. He open his eyes saw something amazing.

It's been days after the battle of the Red Death. Days since Dragons and Viking united and days since, the young boy, Hiccup was gravely injured defeating the Red Death. He's recovering well. His life is okay for now. Has a good relationship with Astrid and the other teens. But everything changes when he discovered something secret about his life.

Everyone on Berk believes Toothless to be the last Night Fury, the only one of his kind left. But all that changes when a black dragon appears on the island, attacking livestock and threatening the vikings! Hiccup goes to pacify the dragon only to find a beautiful creature with blue eyes and retractable teeth... Another Night Fury, and this one is a female! She doesn't like humans, though, and when she flees in fear, Hiccup and Toothless have to get her back. Even if that means they have to fight other dragons, enter the Sanctuary's deepest secret and find the truth behind Comet's horrible scar. Because if they don't, the race of Night Furies is doomed... Praise for Comet Nights: Comet Nights is a very good fanfiction. I think that it should be made into a movie, or a HTTYD mini series on Netflix! - @jayfeather44 I wouldn't be able to even tell whether this is an official story by DreamWorks, or an enormously successful fanfiction. It really takes you to Berk and tells the life of the last female Night Fury, and how much she means to save their tribe. I am astonished by RainbowPhoenixWrites's work, it truly inspires me. - @Tsunami_Holmes

Early 2016 fanfic, which inspired the 3rd installment, "How To Train Your Dragon: The Hidden World". Hiccup and Toothless are now chief and an alpha. Hiccup married Astrid and they all live happily on Berk, researching the dragons and finding new species. But then, they embark on a very unusual adventure, to solve the mystery of the Fury...

Part 1: Hiccup runs away with Toothless when Gobber announces that he will be killing the Monstrous Nightmare. Three years later, he flys back to Berk when he finds out one of his mortal enemies plan to invade it and kill everyone he loves. Will he succeeded? How will the village react? Part 2: It's been two years since with war with BloodFury but now they have a new threat to the dragons, Drago Bludvist and Hiccup has to stop him. Along his journey he finds out his mother is still alive and is the one who has been attacking Drago, however Valka has been getting help with this...who could it be?

Everyone knows the story of Hiccup and how he trained a dragon. Ever know how the dragon trained him? Ever wonder the Night furies past? Well, that's my story. I never used to be called Toothless. The name was Phoenix, named after a star cluster. Born into a world where it was Viking against dragon. Well, me and my best friend changed all that. Before any of that happened though, I have another story. The story of just how I became the best friend to an enemy and just why I held back the kill I yearned. ~I don't own anything owned by DreamWorks~ Story - ©Moonstone360
